Over the past century, there has been a notable development in the intelligence sector in the United States. According to the Hill newspaper, American IQ scores climbed by an impressive 30 points, reflecting significant cognitive gains across generations.
This article will take a dig into the current state of IQ in America, exploring average scores nationwide and by state. We’ll examine the top-performing states those with lower scores, and discuss the factors that may influence these variations.
What Is The Average IQ In The United States?
The average IQ in the United States stands at 99.6, placing it slightly below the global average of 100. This score represents a national average, but it’s important to note that IQ levels vary significantly from state to state. These variations reflect the diverse educational, economic, and cultural landscapes across America.
The US ranks 29th position in the world when it comes to average IQ scores. Japan stands on top with an average IQ score of 106.48, while Nepal is at the last with a 42.99 IQ score.
Average IQ Score In The US By States
There are 50 states in the US. Each state in the US has its own unique IQ profile, influenced by a variety of factors, including education systems, economic conditions, and demographic makeup. Let’s take a closer look at how different states stack up in terms of average IQ scores.
Top 10 US States With Higher IQ Scores
The following states boast the highest average IQ scores in the nation:
| Rank | State | Average IQ Score |
|---|---|---|
| 1 | New Hampshire | 103.2 |
| 2 | Massachusetts | 103.1 |
| 3 | Minnesota | 102.9 |
| 4 | Vermont | 102.2 |

| 8 | Washington | 101.5 |
| 9 | Connecticut | 101.2 |
| 10 | Nebraska | 101.2 |
These states consistently perform well in various measures of cognitive ability and educational achievement. Many of them are known for their strong public education systems and high levels of educational attainment among their populations.
Top 10 US States With Lower IQ Scores
On the other end of the spectrum, these states have the lowest average IQ scores:
| Rank | State | Average IQ Score |
|---|---|---|
| 50 | New Mexico | 95 |
| 49 | Louisiana | 95.2 |
| 48 | Mississippi | 95.8 |
| 47 | Alabama | 96.4 |
| 46 | Nevada | 96.6 |

| 44 | Arkansas | 97.1 |
| 43 | West Virginia | 97.2 |
| 42 | Texas | 97.4 |
| 41 | South Carolina | 97.8 |
It’s crucial to approach these rankings with nuance and context. Lower average IQ scores don’t necessarily reflect the potential or abilities of individuals within these states. Instead, they often point to broader systemic issues and challenges in education, economic opportunity, and access to resources.

How Does Average American IQ Compare To Other Countries?
The average IQ in the United States stands at 99.6, which places it in a respectable position globally but not at the top of the rankings. This score puts the U.S. slightly below the often-cited global average of 100. When compared to other nations, the United States ranks 29th out of the countries listed in the 2024 study by researchers Richard Lynn and David Becker.
The U.S. average IQ is lower than many East Asian and European countries but higher than most countries in South America, Africa, and parts of Asia. For context, Japan leads the list with an average IQ of 106.48, while several Western European nations like Germany (100.74) and the Netherlands (100.74) score slightly higher than the United States.
Top 20 Countries With The Highest IQ
The following table presents the top 20 countries with the highest average IQ scores. These nations represent a mix of East Asian, European, and North American countries, showcasing the global distribution of high cognitive performance.
| Rank | Country | Average IQ |
|---|---|---|
| 1 | Japan | 106.48 |
| 2 | Taiwan | 106.47 |
| 3 | Singapore | 105.89 |

Factors Determining IQ Scores In The US
Several key factors contribute to the variations in IQ scores across the United States:
- Education Quality: States with robust public education systems tend to have higher average IQ scores. This includes factors like school funding, teacher quality, and curriculum standards. For example, Massachusetts, which ranks second in average IQ, is often praised for its excellent public schools.
- Socioeconomic Status: There’s a strong correlation between economic prosperity and cognitive performance. States with higher median incomes and lower poverty rates often see higher average IQ scores. This link likely stems from better access to educational resources, healthcare, and nutrition in more affluent areas.
- Cultural Attitudes Toward Education: Some regions place a higher cultural value on academic achievement and intellectual pursuits. This can lead to more parental involvement in education and higher expectations for students, potentially boosting cognitive development.
- Access to Early Childhood Education: States that invest heavily in pre-K and early childhood programs often see cognitive benefits later on. These early interventions can have lasting impacts on brain development and academic success.
- Environmental Factors: Exposure to environmental toxins, such as lead, can negatively impact cognitive development. States with stricter environmental regulations and better infrastructure may see cognitive benefits in their populations.
- Demographic Makeup: The age distribution of a state’s population can influence average IQ scores. States with younger populations might see lower averages, as IQ tends to increase into adulthood before declining in later years.
- Brain Drain and Migration Patterns: Some states experience “brain drain,” where highly educated individuals move to other areas for better job opportunities. This can impact average IQ scores in both the states losing and gaining these individuals.
- Healthcare Access: States with better healthcare systems may see cognitive benefits in their populations. This includes access to prenatal care, which can significantly impact early brain development.
- Nutrition: Access to healthy food and good nutrition plays a role in cognitive development. States with higher rates of food insecurity or poor dietary habits may see impacts on average IQ scores.
- Technology Access: In our increasingly digital world, access to technology and the internet can impact cognitive skills. States with better broadband infrastructure and technology integration in schools may see benefits in problem-solving and information processing skills.
Can You Increase Your IQ?
While IQ is partly influenced by genetics, research suggests it can be improved to some extent. Regular mental stimulation, learning new skills, and maintaining a healthy lifestyle can potentially boost cognitive abilities.
Education, proper nutrition, and reducing stress may also positively impact IQ scores. However, dramatic increases are rare, and improvements are typically modest. The key is consistent effort in challenging your mind and maintaining overall brain health.
Mindvalley offers brain training courses that may boost cognitive skills, potentially contributing to improved IQ performance. There are more than 100+ courses that you can try to improve your IQ.
Conclusion: The Average American IQ Score Is 99.6 In 2024
The average American IQ of 99.6 represents a complex tapestry of cognitive performance across the nation. While some states consistently rank higher in IQ measures, it’s essential to remember that these scores reflect averages and do not define individual potential or worth.
The factors influencing IQ scores – from education quality to environmental conditions – highlight the interconnected nature of cognitive development and societal well-being.
Ultimately, the story of American IQ is one of progress, challenges, and ongoing evolution. By continuing to invest in education, health, and equitable access to resources, the US can unlock the full cognitive potential of all Americans, regardless of where they live or their background.
